Question

所以我的情况是这样的。我有以下查询来获取数据库中的帖子，void setEnabledWidgetsInLayout(QLayout *layout, bool enabled) { if (layout == NULL) return; QWidget *pw = layout->parentWidget(); if (pw == NULL) return; foreach(QWidget *w, pw->findChildren<QWidget*>()) { if (isChildWidgetOfAnyLayout(layout,w)) w->setEnabled(enabled); } } bool isChildWidgetOfAnyLayout(QLayout *layout, QWidget *widget) { if (layout == NULL or widget == NULL) return false; if (layout->indexOf(widget) >= 0) return true; foreach(QObject *o, layout->children()) { if (isChildWidgetOfAnyLayout((QLayout*)o,widget)) return true; } return false; }中使用的单词来自LIKE，而input text来自month。所以，当我在select tag中输入Brescia时，它会使用input box来获取帖子，这是正确的结果，但是当我选择brescia和month时，它只会返回有brescia的帖子，不会进行月份扫描。我有月份字段，如：brescia格式man_date。

Answer 1

＆＃34;％＆＃34; sign用于在模式之前和之后定义通配符（缺少字母）。因此，如果您想要过滤＆＃34; Brescia＆＃34;，请不要使用通配符。

我认为你在OR条款中缺少括号： -

SELECT wp_posts.*, MONTH(wp_posts.man_date) as month 
FROM wp_posts 
INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) 
INNER JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) 
INNER JOIN wp_locations ON (wp_posts.ID = wp_locations.post_id) 
WHERE 
    wp_term_taxonomy.taxonomy = 'tipo_manifestazione' 
    AND 
    wp_term_taxonomy.term_id = 97 
    AND 
    wp_posts.post_type = 'manifestazione' 
    AND 
    MONTH(wp_posts.man_date) = 4 
    AND 
    wp_posts.post_status = 'publish' 
    AND 
    wp_posts.vip = 'NULL' 
    AND 
    ( 
        wp_locations.continente LIKE '%Brescia%' 
        OR 
        wp_locations.nazione LIKE '%Brescia%' 
        OR 
        wp_locations.regione LIKE '%Brescia%' 
        OR 
        wp_locations.citta LIKE '%Brescia%' 
        OR 
        wp_locations.luogo LIKE '%Brescia%' 
    )
    GROUP BY wp_posts.ID 
    ORDER BY wp_posts.ID DESC

SELECT FROM TABLE WHERE LIKE和MONTH（）= 4
